Application filed November 21, 1916. Serial No. 132,605.

To all whom it may concern:

Be it known that I, Davin l). GoimoN, a citizen of the United States, and a resident ofChicago, in thdcom-rty of (look and State same, reference being bad to the accon'lpanying drawings, and to the characters of reference marked thereon, whiclnform a part of this specification.

This invention relates to electrical sockets of the pull'chnin type and particularly-to guides for the pull chains or cords thereof.

An object of my invention is the provision of improved means for attaching chain guides to pull sockets in a simple and efficient manner whereby'to enhance the practicability and commercial value of such sockets and to enable the guides to be quickly applied to or" removed from the sockets.

further object of my invention is the pn vision in an electrical socket having separable top and bottom members forming an insulating switch carrying body, of an improved chain guide which is detachably secured to said body members and adapted to assist in retaining such members in assembled relation. I

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which-- i Figure 1 is a side elevation of a socket en'ibodying the invention, with a portion of the shell broken away. Fig.2 is a top plan view thereof with the shell cap removed.- Fig. 8 is a side elevation of the socket with r the shell and chain guide removedrand Fig.

4% is a view of a chain'guide embodying the] invention. I

Referring to the drawings, 1 and 2 designate the base and cap members,- respectively, of the shell of an electrical socket, which members may be separately secured together in any suitable oeconvenient manner, as is .well understood in he art. The switch carrying body of the socket comprises thebase and cap mei'nbers 3 and 4., respectively, which are mounted one on top of the other inclose the switch mechanism. These body members may be separably secured together by spring fingers or in any other suitable. manner (not shown) as well understood in the art, or they may be placed loosely one on top of the other and held in assembled relation by the inclosing shell, in conjunction with themeans hcreinaftendescribed. An insulating lining 5 is disposed between the shell and switch body as is customary in sockets of this character.

The pull chain (3 for operating the switch mechanism extends out from the interior of the switch body through an opening 7, pro-. vided in one side thereof, and thence through a chain guidi- 8, which extends from the outer end of the opening 7 out througha registering opening 5) provided in the shell base land insulating lining 5, said opening extending to the upper ends of said parts and being clo ed above the guide by the shell cap when mounted on the base 1, as is customary in sockets of this character.

The chain guide 8,111 the present instance, is of bell form and is provided atits inner to fit against the side otthe svitch body. The plate 10 is elongated lengthwise. of the switch body to adapt it to extend in both directions beyond the point of division of end with a base plate 10, which is adapted the members of said body, and has one end,

the upper in the present instance, provided with inwardly turned L-shaped fingers 11 which project into a recess or pocket 1). provided in a side of the body member4 and have their angled ends fitting into registering sockets 13 provided in the base wall of said recess. it is thus evident that the upper end of the plate 10 is adapted to have booked engagement with the bodymember t to prevent a transverse witlnlrawiug of such fingers ,from engagement with; the body member except when the fingers are moved upward to disengage their hooked or angled ends from within the holding sockets 13. While. it is preferable to provide the fingers 11. with the angled end portions for hooked engagement with the socket body,

these fingers may be made straight if de sired without departing from the invention.

The opposite end of the plate 10 is pro vided with an inturned finger 14, which is adapted to project within a registering rethe spirit of 25 lining may be cut away to receive said plate.

cess 15 provided in the body membera3 in outwardly spaced relation to its inner end. The space between the .bottom walls of the recesses 12 and 15 is substantially equal to the space between the fingers 11 and 14 so that such fingers when projected into the respective recesses coact with the bottoms thereof in opposed relation and serve to retain the members of the socket body in as seinbled relation. Itis apparent that in engaging the chain-guide plate 10 with the socket body, if the fingers 11 are of angled form, it is necessary to first place the fingers 11 in hooked engagement with the recess 12 j and recesses 13 thereof and then to swing the opposite end of the plate inward toward the socket body'to project the finger 14 into the recess l5.- The plate 10 is then retained to the socketbody in this position by the shell base 1 and lining 5, when slipped over said body, or by the shell alone if the plate 10 is too thick or projects too great a distance from the side of the socket body to permit the interposition of the lining between the plate and shell, in which case the It is evident that I have provided a simple and efiicient means for attaching a chain guide to a socket and that it is also adapted to serve as a means for retaining the members of the socket body in assembled relatransversely from its inner end in opposed relation, said fingers bearing inward against a side of said body and angled at their ends to enter registering portions of respective body membersto prevent a longitudinal separation thereof.

2. In an electrical body having separable base and cap members with each member provided in a side thereof with a recess which is outwardly spaced from its inner end, and a chain guide having aplate at its inner end for resting against the outer side portion of said body and having tions for insertion into the recesses of said members whereby the plate and fingers cooperate with the adjacent walls of the recesses to retain the body members in assembled relation.

3. In an electrical socket, an insulating body provided in a side thereof with longitudinally spaced recesses, and'a chain guide having a plate at its inner end for resting against the outer side portion of said'body and having fingers at its ends for projecting into respective recesses with a finger at one end angled and in hooked engagement with a wall of its recess.

4. Inan electrical socket, an insulating body. having separable base and'cap portions each provided with a. recess in aside thereof in outwardly spaced relation to its inner end, and a chain guide having'a plate at its inner end for restingagainst the outer side portion of said body in spanning relation to the dividing line between its members and having hooked means at one end} for projecting into and interengakgin'g with a wall of one of said recesses an at its other end for of said recesses.

In testimony whereof, I have hereunto signed my name to this specification.
